2006 3L CRD blowby gas issue

Hi

I'm new so I hope I've got this post where it should be.

I have a 2006 3L CRD, I just had the new turbo intake and a Provent 200 catch can installed hoping to eliminate any possible future problems. Anyway, after hearing alot of air leak noises and discovering alot of exhaust gases leaking from the Provent, I headed back to the mechanic and discovered that the problem is being caused by excessive crank case blowby gases. Basically the Provent is venting pressure through the release valve. Mechanics diagnosis, "worn engine, too bad". The engine has done 180K and has been regularly serviced, so I'm finding this a little too hard to chew. If anyone has had similar issued I'd love to hear from you.

Cheers
Rick

Make sure the hose from the crankcase goes in the bottom part of the Provent. The top one goes to the turbo inlet.

Throw the proevent into the bush and vent to the atmosphere.I love the smell of crankcase venting in the morning,smells like Prius pis**ng off power.

Another crd owner had a pressure valve that kept popping so he also went to atmospheric venting

Thanks for the reply's,

Not a big fan of venting to the atmosphere, and I don't think the local authorities here in Aus would be either. Tony, you say plumb from crank to bottom of Provent, mine has been plumbed opposite to this, but the instructions from the supplier were top inlet in, and bottom out, so this seems to be correct. Maybe they are opposite here??? My main concern with this issue is the condition of my engine, I can't believe the thing can be worn out at 180k kilometers, that's only about 110k miles. I'm keen to know if anybody else has experienced this excessive blowby with this engine. A local turbo repairer has suggested a good engine oil flush and a decarbonising fuel additive to deglaze the cylinder bore's. Might give that a go, and yeah Jediknight I think I'll take care of this job myself.
Cheers and thanks again.
